Cinera

Download, and prepare the parser

1. git clone git@gitssh.handmade.network:Annotation-Pushers/Annotation-System.git
2. cd Annotation-System/hmmlib
3. make
4. cp hmml.a hmmlib.h ../cinera/
5. cd ../cinera/

Note: For each parser update, remember to make and copy it into place.

Install the dependency

1. curl

Build

1. $SHELL cinera.c

Configure the server

If you enforce a strict Content Security Policy and X-Frame-Options in your server configuration as recommended by Security Headers, you may enable Cinera to function by making two small tweaks:

add_header Content-Security-Policy "default-src … https://www.youtube.com https://s.ytimg.com";
add_header X-Frame-Options "ALLOW-FROM https://www.youtube.com";

Note: For more information about these and other security headers, see Scott Helme's articles Content Security Policy - An Introduction and Hardening your HTTP response headers.

Run

Single Edition operation

cinera test.hmml

This simply generates an HTML file (and updates cinera_topics.css if needed) from test.hmml and outputs to out.html (configurable with -o).

Project Edition operation

cinera -p ProjectID

Setting the ProjectID with the -p flag triggers Project Edition. In this edition Cinera monitors the Project Input Directory for new, edited and deleted .hmml files, and generates one table of contents / search page and a player page each for valid sets of annotations (or removes them, if needed).

By default all directories - input and output - are set to the current working directory. Typical operation will involve setting these flags:

-d Project Input Directory, the directory where the .hmml files reside
-r Root Directory, path shallower than or equal to the CSS, Images and JS
   directories
-R Root URL, corresponding to the Root Directory (optional if the Output
   Base Directory resides in the Root Directory)
-c CSS Directory, relative to Root
-i Images Directory, relative to Root
-j JS Directory, relative to Root
-b Output Base Directory, location of the table of contents / search page
-B Output Base URL, corresponding to the Output Base Directory
-t Template Directory
-x Index Template Location, relative to Template Directory
-y Player Template Location, relative to Template Directory

Templates

Index Template

• <!-- __CINERA_INCLUDES__ --> the necessary .css and .js files
• <!-- __CINERA_INDEX__ --> the table of contents, and search functionality

Player Template

• <!-- __CINERA_INCLUDES__ --> the necessary .css and .js files, and charset setting
• <!-- __CINERA_MENUS__ --> _ the menu bar that typically appears above the player in my samples
• <!-- __CINERA_PLAYER__ --> the player
• <!-- __CINERA_SCRIPT__ --> the filter state objects and .js file, which must come after both the MENUS and PLAYER tags

Optional tags available for use in your Player Template

• <!-- __CINERA_TITLE__ --> the day / episode name, intended to be used inside your own <title> element, but may be used wherever and as many times as you want on your page
• <!-- __CINERA_VIDEO_ID__ --> the unique identifer of the video as provided by the VoD platform

Other available tags

• <!-- __CINERA_PROJECT__ --> the full name of the project
• <!-- __CINERA_PROJECT_ID__ --> the ID of the project
• <!-- __CINERA_THEME__ --> the theme of the project
• <!-- __CINERA_URL__ --> the URL where we have derived the page will be publically accessibly, only really usable if BaseURL is set (-B)
• <!-- __CINERA_CUSTOM0__ -->
• <!-- __CINERA_CUSTOM1__ -->
• <!-- __CINERA_CUSTOM2__ -->
• ⋮
• <!-- __CINERA_CUSTOM15__ --> Freeform buffers for small snippets of localised information, e.g. a single <a> element or perhaps a <!-- comment --> They correspond to the custom0 to custom15 attributes in the [video] node in your .hmml files 0 to 11 may hold up to 255 characters 12 to 15 may hold up to 1023 characters

Feel free to play with templates to your heart's content. If you do anything invalid, Cinera will tell you what's wrong.
